Introduction

Tantalum capacitors are electronic components used in various applications, such as consumer electronics, automotive electronics and aerospace products. The M39003/01-2698, from AMS Technologies, is a radial, surface mounted, miniature tantalum capacitor. It is a monolithic,surface-mountable device for use in high-reliability applications. Although standard capacitors are used in most applications, some applications require the use of special materials and construction to achieve desired performance. The M39003/01-2698 is a specialized type of tantalum capacitor, designed to meet the stringent requirements of military and space applications where quality and reliability are paramount. It is used where size and light weight are critical and where high performance is needed.

Application Field

The M39003/01-2698 has many applications. It is used in products such as personal computers, mobile devices, servers, medical devices, automotive and aerospace systems, defense systems and other mission-critical applications. In consumer electronics, it is used to provide the necessary electrical current for the signal processing that powers today’s sophisticated digital audio, video and gaming products. Automotive electronics applications include engine control systems, navigation systems, braking systems and air bag controllers. The M39003/01-2698 is also used in aircraft and space vehicle avionics and instrumentation systems. Additionally, it is used in electronic systems that must be able to operate in high temperature and shock or vibration environments. It is often found in harsh chemical and hostile environmental conditions, such as those encountered in medical and industrial applications.

Working Principle

Tantalum capacitors are polarized devices, meaning that electrical energy flows in one direction only. A tantalum capacitor is constructed using a tantalum powder which is compressed, forming a disk shape. A layer of tantalum oxide, which acts as an electrical insulator, is formed over the surface of the disk. Electrodes are then attached to each end of the disk and a permanently sealed, protective coating is applied over the exterior to protect the assembly from the environment. The M39003/01-2698 is a highly reliable device capable of storing a significant charge for long periods of time. It has a high capacitance-to-volume ratio, meaning that it can hold a large electrical charge in a relatively small package. The capacitor also has a low equivalent series resistance (ESR), which is important in applications where precision timing is required.

Conclusion

The M39003/01-2698 from AMS Technologies is an advanced type of tantalum capacitor designed for use in mission-critical applications where dependability and performance are essential. It is a reliable, miniaturized device capable of providing a consistent charge over an extended period of time. It has a high capacitance-to-volume ratio and a very low ESR. Additionally, it is ruggedly designed to operate in extreme environments. It is widely used in computers, automotive electronics, aerospace systems and other high-reliability applications.
